INSAG reports

Safety, INSAG Report 75-INSAG-4—International Atomic Energy Agency, Vienna, 1991. 

Safety objectives are fixed for every nuclear installation. These objectives should be measurable, both qualitatively and quantitatively, and they should include prevention of severe accidents and mitigation of the consequences, should prevention fail, as it has been clearly stated in a series of IAEA INSAG reports. When setting safety objectives, other factors (notably non-fatal health effects) should also be taken into account, as learned from the historical severe accidents. 

Other safety related IAEA publications are issued as Radiological Assessment Reports, the International Nuclear Safety Group s INSAG Reports, Technical Reports and TECDOCs. The IAEA also issues reports on radiological accidents, training manuals and practical manuals, and other special safety related publications. Security related publications are issued in the IAEA Nuclear Security Series.

Other IAEA series that include safety related sales publications are the Technical Reports Series, the Radiological Assessment Reports Series and the INSAG Series. The IAEA also issues reports on radiological accidents and other special sales publications. Unpriced safety related publications are issued in the TECDOC Series, the Provisional Safety Standards Series, the Training Course Series, the IAEA Services Series and the Computer Manual Series, and as Practical Radiation Safety Manuals and Practical Radiation Technical Manuals. 

Since then, a report has been issued by the International Nuclear Safety Group (INSAG-75). This Group s report makes a large number of recommendations and lists a number of conclusions. A selection of these is summarised below.

Reports on safety and protection in nuclear activities are issued in other publications series, in particular the Safety Reports Series. Safety Reports provide practical examples and detailed methods that can be used in support of the safety standards. Other IAEA series of safety related publications are the Provision for the Application of Safety Standards Series, the Radiolo0cal Assessment Reports Series and the International Nuclear Safety Group s INSAG Series. The IAEA also issues reports on radiological accidents and other special publications.

The initiating event, the progress and the consequences of this accident have been described several times, in detail in the relevant Insag-1 report of the IAEA Safety Series No 75 (1986) and, more recently, in Insag-7 (1992). In this section, therefore, only those aspects will be treated which are of signiflcance with respect to the radiochemical aspects of fission product release the question of the longdistance transport of the radionuclides released from the plant will not be discussed.

Since that time, the relevant IAEA programme has focused on the development of guidance to assist Member States in the safety reassessment of operating plants. In addition, INSAG has developed a report on A Common Basis for Judging the Safety of Nuclear Power Plants Built to Earlier Standards, INSAG-8 (1995), which is supplemented by practical guidance issued by the IAEA. 

Safety culture is discussed in a number of IAEA documents, principally INSAG 4, INSAG 15 and Safety Report Series 11 (References 9.18, 9.19 and 9.20), and is intrinsic to the site Licensing Conditions. Safety culture issues are relevant to all stages of the plant life cycle. 

The importance of the concept of defence in depth is underlined in IAEA Safety Standards, in particular in the requirements set forth in the Safety Standards Safety of Nuclear Power Plants Design (NS-R-1) and Safety Assessment and Verification for Nuclear Power Plants (NS-G-1.2). A specific report. Defence in Depth in Nuclear Safety (INSAG-10), describes the objectives, strategy, implementation and future development in the area of defence in depth in nuclear and radiation safety. In the report Basic Safety Principles for Nuclear Power Plants (INSAG-12), defence in depth is recognized as one of the fundamental safety principles that underlie the safety of nuclear power plants.
